Subject: [PATCH] libatomic: Do not enforce march on aarch64

OE passes the right options via gcc compiler cmdline via TUNE_CCARGS
this can conflict between -mcpu settings and -march setting here, since
-mcpu will translate into an appropriate -march, lets depend on that
instead of setting it explicitly

Upstream-Status: Inappropriate [OE-Specific]
